The properties of tsunami wave pressures acting on a coastal dike were studied in a tsunami experimental tank. The results obtained in this experimental study were as follows; 1) the greatest impulsive pressure occurs when a crest of bore-type tsunami just overtops at an upright coastal dike. 2) The greatest continuous pressure of tsunami generally exceeds the value estimated by Tanimoto's formula (1984). 3) An impulsive pressure of tsunami is not so much affected by sea-bottom slope. 4) In addition, an installation of breakwater in the front of a coastal dike is very effective for decrease of wave pressure.
